Answer:
It is commonly known that the settling time of particles with smaller sizes is higher than that of particles with larger sizes. Therefore, the particles with smaller sizes are moved further offshore. Based on this fact, the proper arrangement will be to arrange the particles according to their sizes from those with the largest sizes (nearshore) to those with the smallest sizes (furthest offshore).
